<div id="L_Time" style="visibility: hidden;">
<html:text property="standardMark" value="" onblur="a();">
</html:text>
</div><select property="standarLevel" onchange="F_Select(this)">
<option value="0">老子</option>
<option value="1">儿子</option>
</select>
<script language="JavaScript">   
 function  F_Select(select)   
  {   
          for(iIndex=0;iIndex<select.length;iIndex++)   
          {   
                    if(select.options[iIndex].selected)   
                    {   
                                if(select.options[iIndex].value==0)   
                                {   
                                              L_Time.style.visibility="hidden";
                                                 
                                }   
                                else   
                                {   
                                              L_Time.style.visibility="";
                                              
                                              
                                  }     
                    }                     
          }   
  }  
</script>
当选择老子的时候隐藏，选择儿子的时候出来
